Almendra en Obras I y II is a legendary live album by the Argentine band Almendra recorded at the Obras Sanitarias Stadium in December 1979, it constituted the group's first return after nine years of separation. The presentations were filmed for a film that, although it was never edited, is considered an Art Work due to the reflection of the warmth and energy of those concerts.
The material, the band, the sound, and the presentation of two unreleased gems: "Cambiándome el futuro" y "Vamos a ajustar las cuentas al cielo", which were not included in the album recorded in the studio "El valle interior" the following year, make this work one of the most remembered for the band. The album was out of print and in 2019 it was rescued and remastered to see the light again only in CD format for the fans.
